CHARLES A. BURR, OF ROOKDALE, N EWV YORK.

SAP-SPOUT.

SPECIFICATION forming part of Letters Patent No. 363,280, dated May 17, 188

Application filed January 27, 1887. Serial No. 225,683. (No model.)

To aZZ whom it may concern.-

3e it known that I, CHARLES A. BURR, a citizen of the United States, residing at Rockdale, in the county of Ohenango and State of Fig. 3 is a plan view of the same.

Referring to the drawings by letter, A designates the spout, which may be of any desired material, but is preferably constructed of metal. As shown in Figs. 2 and 3, the spout is hollowed out through nearly its entire length, so as to provide the trough a, through which thesap passes on its way to the bucket. Projecting from the center of the rear closed end of the spout is a tapered extension or spike, B, which enters the tree and serves to hold the spout in its place. It will be seen upon reference to the drawings that the rear closed end, 0, of the spout is cylindrical and is in a line with the extension B, while the trough a, or spout proper, is formed at a slight angle thereto.

In applying my device to a tree the spike B and rear cylindrical end of the spout are driven into the same in a horizontal position, so that the trough will have a slight downward inclination toward the outlet end,whereby the passage of the sap to the bucket will be somewhat facilitated. Near the extreme rear end of the spout I provide it with an annular flange, D, which limits the movement of the spout into the tree. A short distance in front of this annular flange I provide, on the opposite sides of the spout, the lugs E E, and on the upper side of the spout I slightly cut away or depress the space between the annular flange D and the lugs E, as shown at F.

These lugs E are made of the proper dimensions to have their bases extending from top to bottom of the spent and effectually prevent the bucket slipping off the spout, as will be readily understood.

G designates an opening or passage formed through the rear closed end of the spout, through which the sap passes from the tree into the trough a. Any desired number of these openings may be provided.

In applying my device to a tree I first bore a hole, as H, in the tree, said hole having a diameter equal to or slightly greater than the diameter of the cylindrical portion 0 of the spout, and being somewhat less in length than the length of the spike B. The said spike is then inserted in said opening and the spout driven into the same until the annular flange D fits tight against the trunk of the tree. The spike B will now have entered the wood of the tree back of the hole H, and the .spout will be held in the wood firm and secure from being forced out by frost and freezing. The bucket is held upon the spout between the flange D and the lugs E, and will be held from slipping off the spout by the said lugs E. The sap passes from the end of the trough into the bucket, and when one bucket is filled it is removed and replaced by another.

It will be readily seen that the hole H acts as a reservoir in which the sap collects, and from which it cannot escape, because the cylindrical end 0 of the spout completely fills its mouth.

I am aware that it is not broadly new to construct a sap-spout with a spike at its rear end at a slight angle to the trough, and to provide lugs on the opposite sides of the trough. Such a device is shown in the patents to O, 0. Post, No. 117,326, granted July 25, 1871; No. 117,457, granted July 25, 1871, and No. 348,581, granted September 7, 1886,.and I make no claim to the construction therein shown. My device differs from those used by Post in having the bases of the lugs on the sides extending entirely from the top to the bottom, and having a straight cylindrical portion at the rear end of the trough, from which the spike projects, and in having the base of the spike of a less diameter than the rear closed end of the trough.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, I jeeting from the rear closed end of the trough, is-- J the diameter of the base of the spike being The improved sap-spout herein described 1 less than the diameter of the closed end of the I 5 and shown, consisting of a trough having a I trough, substantially as specified.
